Abstract:	This paper studies the dispersion characteristics of a modified photonic band-gap slow-wave structure with an open boundary by simulation and experiment. A mode launcher with a wheel radiator and a coupling probe is presented to excite a pure TM₀₁-like mode. The cold test and simulation results show that the TM₀₁-like mode is effectively excited and no parasitic modes appear. The dispersion characteristics obtained from the cold test are in good agreement with the calculated results.

Keywords:	modified photonic band-gap slow-wave structure TM₀₁-like mode cold test
